Is VNA 675116 the Standard for Measuring Cold Index in Valves?

[gabriel]

Hi,
I work with valves and one of our customer send me an oring specification. this file says that the index (or coefficient) of cold is -50°C and it was measured with differential scaning as per VNA 675116. I have never heard something about it.
thanks

Hi gabriel,
VDA 675116, not VNA. It's a German standard, but that's all I can tell you.

Yes, I am familiar with VNA (Vector Network Analyzer) standard. It is commonly used in the testing and characterization of electronic components, such as valves. The VNA 675116 refers to a specific model or type of VNA that was used to measure the oring specification at a temperature of -50°C. This standard ensures accurate and reliable measurements by using differential scanning techniques. It is important to follow this standard in order to ensure the quality and performance of the valves. I suggest contacting the customer for further clarification or consulting with a VNA expert for more information.
